In cases where the style of ornament permits of it, patera covers are used instead of pelleting. shows the jointing of shaped spandrails, etc., to carcase ends of light portable cabinet work, etc. A hole is bored about 3⁄8 in. deep into the end, and a screw is used to hold the shaping in position. After fixing the rail a small turned button, called a turned patera, is inserted in the hole, thus giving an ornamental finish, as shown in the front view. The turned patera is driven fairly tightly into the hole, but not glued. When it is required to take the article apart a chisel is carefully inserted under the edge of the patera to remove it, and the screw can then be taken out. This method is often used for the construction of light hanging bookcases and similar objects. For a bookcase having an end 8 ins. wide three of these turned buttons and three screws would be used to secure the shelf to the end. Pateras in different styles may be purchased from any dealer in woodworking sundries.
